Abstract

Time perception has been of interest in neuropsychology research for decades. However, in recent years the topic has gained interest in exercise physiology. Research has shown that time perception can be distorted by multiple factors: sex, vital signs, exercise intensity, and attentional effects. Conflict in the literature exists as studies have found the perception of time to be underestimated or overestimated as these factors interplay with exercise. As only a few studies have analyzed exercise and time perception, there are gaps in understanding what truly influences time perception. Additionally, many studies have not investigated sex differences in time perception while performing a bout of exercise. Additional research is needed to grasp time perception's psychological and physiological interplay. The findings of this study highlight a significant time underestimation during 20 and 30-s intervals during submaximal and maximal exercise, with the greatest underestimation being at 30-s undergoing a maximal intensity contraction.
